The sensor has at least one magnetic field sensor element and a signal processing circuit. The speed sensor arrangement having a permanent magnet and the magnetic field provided by the permanent magnet is modulated by the ferromagnetic encoder at least during a movement of the encoder and the magnetic field sensor element of the sensor detects this modulated magnetic field. The magnetic field sensor element is implemented as a GMR sensor element or as a TMR sensor element and the speed sensor arrangement is implemented such that the permanent magnet is arranged at a defined minimum distance from the magnetic field sensor element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"GMR or TMR sensor used with a ferromagnetic encoder","description":"A speed sensor arrangement, implemented in particular as a wheel rotation speed sensor arrangement, including: a sensor and a ferromagnetic encoder.
